Clicking sound when trying to start Rover 25?

Yes, there is a solenoid on the starter motor and it usually clicks if the battery is very low on power - enough to energize the solenoid but not enough to turn the engine over. Batteries struggle when it is as cold as this , particularly if you haven't used it for a day or two. If the battery is more than three years old it's probably had it - but if you can charge it up (or get a jump start and go drive for 20 minutes) it may recover sufficiently.
